Human Body Organ Systems and VA Disability Systems Quiz

• The human body is made up of 11 organ systems that manage all the essential body functions.
• Each organ system is interconnected and works together to try to create homeostasis or a state of balance within the body.
• The VA uses 14 disability systems to rate disability claims.
• Each disability system is similar to the body system, but is separated differently for rating purposes.
• The VA defines diseases and disorders associated with the different body systems.
• The Musculoskeletal system includes both the skeletal system and the joint system.
• The skeletal system supports and protects the body's internal organs, and connects to the musculoskeletal system.
• The joint system allows for movement and allows us to interact with the world around us.
• The musculoskeletal system is a large and complex system, and can be affected by a variety of diseases and disorders.
• The muscular system is responsible for carrying out the actions and movements caused by messages sent from our brains through our nervous system.
• Skeletal muscles are also responsible for maintaining posture and producing heat.
• When muscles lack appropriate levels of oxygen they can cramp and tear, creating pain.
• When not used they can atrophy and become useless.
• Diseases and disorders of the muscular system include muscular dystrophy; fibromyalgia; tendinitis; multiple sclerosis; and muscle strain or sprains; hernias.
